Abstract
The invention discloses acidified chlorite. According to the technical scheme, the acidified chlorite is characterized by consisting of chlorite, sulfuric acid, instant sodium silicate, polyvinyl alcohol, hydroxypropyl methyl cellulose and sodium carbonate. A production method for the acidified chlorite comprises the steps of feeding acidified chlorite ingredients into a mill, and milling to obtain powder, namely the acidified chlorite. According to the requirement of product quality, the pH value of the acidified chlorite is adjusted by adopting the sodium carbonate. The method is simple and feasible. By fully utilizing solar energy, alternating wind and rain and alternating cold and heat, the natural weathering effect of raw chlorite is promoted, the disintegrating effect of the raw chlorite is improved, and dispersion of the raw chlorite is accelerated. The acidified chlorite has relatively good adsorptivity, thixotropy, lubricating property, thermal stability and plasticity. The acidified chlorite is suitable for producing adsorbents, suspending agents, lubricating agents, linoleums, papers, pesticides and fillers of firefighting products.
Description
Technical field
The present invention relates to acidification, be specifically related to the chlorite after a kind of acidifying.
Background technology
Chlorite is a kind of aluminium silicate mineral, and normal and spontaneous quartzy symbiosis, is needle shape, bobbles shape, rose-shaped, and the occurrence in hole has hole liner and pore filling.General needle shape chlorite mostly is hole liner and is wrapped in particle surface, bobbles shape and rose-shaped being filled in hole.Chlorite can be by Mineral Transformation such as biotite, hornblende, montmorillonites, and authigenic chlorite is generally rich in high price iron ion, and easily produce precipitation with the acid solution effect such as HCL in drilling fluid, and cause reservoir damage, be acid sensitivity mineral.
In chlorite mining area, usage mining machine carries out mechanical mining chlorite raw ore, excavate out be a kind of compact mass chlorite raw ore, can not be directly used in acidification, be to adopt pulverizer to be broken for tiny particle mostly, be easy to destroy the crystalline structure of chlorite.
After acidification, do not carry out follow-up complementary modification, can not improve the quality of chlorite product comprehensively.
Summary of the invention
The object of the invention is to overcome weak point in prior art, the chlorite after a kind of acidifying is provided.
Chlorite batching after acidifying is made up of chlorite, sulfuric acid, quick dissolved sodium silicate, polyvinyl alcohol, Vltra tears and sodium carbonate.
The production method of the chlorite after acidifying: by abrasive dust in the chlorite batching input grinding machine after acidifying, the meal after abrasive dust is the chlorite after acidifying.
Chlorite is extensively present in occurring in nature using forms such as particulate aggregate, crystallization lamellar bodies as the product of normal metamorphism, sedimentation and hydrothermal alteration effect conventionally.Its crystalline structure, physical properties, Chemical Composition and geological occurrence are in close relations, have certain metallogenic relation.
It is 98% the vitriol oil that sulfuric acid is selected concentration.
Quick dissolved sodium silicate is white pulverulent material, can be dissolved in fast water, has that cohesive force is strong, intensity is higher, acid resistance, good heat resistance, the feature of alkali resistance and poor water resistance.
Polyethenol series white solid, that external form is divided is cotton-shaped, particulate state, Powdered three kinds; Nonpoisonous and tasteless, particulate state can be dissolved in 80--90 DEG C of water, pulverously after other powders pre-dispersed, can dissolve at normal temperatures.There is good viscosity, polymerizability, cohesiveness and water-retentivity.
Vltra tears has thickening capabilities, salt discharge, pH stability, water-retentivity, dimensional stability, good film-forming properties and the feature such as resistance to enzyme, dispersiveness and cohesiveness widely.
Sodium carbonate has the general character and the thermostability of salt, soluble in water, and its aqueous solution is alkalescence, in the present invention for adjusting the chlorite pH value after acidifying.
The present invention is achieved by following technical proposals:
1, the batching of the chlorite after acidifying is made up of following component by weight percentage: chlorite work in-process 90～98%, quick dissolved sodium silicate 0.1～5%, polyvinyl alcohol 0.1～5%, Vltra tears 0.01～3% and sodium carbonate 0～3% after acidifying.
2, the production method of the chlorite after acidifying: by abrasive dust in the chlorite batching input grinding machine after acidifying, particle fineness≤0.074 millimeter, the meal after abrasive dust is the chlorite finished product after acidifying.
3, the half-finished production method of the chlorite after acidifying: in the stirrer (1) first chlorite after weathering input having been turned round, then dilute sulphuric acid is slowly added and carries out acidification in the chlorite after weathering; (2) by the chlorite after acidification, push as chlorite flap thickness≤3 millimeter of chlorite flap by twin rollers; (3) chlorite flap is transported to roasting in rotary type stoving oven, roasting time is 1～3 hour, maturing temperature is controlled at 250～350 DEG C, chlorite flap water content≤5% after roasting, chlorite flap after roasting is the chlorite work in-process after acidifying, and PCm is weight percentage.
4, the batching of chlorite flap is made up of following component by weight percentage: the chlorite 55～75% after weathering and dilute sulphuric acid 25～45%.
5, the batching of dilute sulphuric acid is made up of following component by weight percentage: the vitriol oil 1～5% that concentration is 98%, and water 95～99%, the vitriol oil per-cent that concentration is 98% is weight percentage.
6, chlorite raw ore need to be through two time weathering more than winter, chlorite the weathering that is fine particle from the raw ore disintegration of large block compact, pick obvious visible barren rock piece, vegetable fibre and other earth impurity, chlorite particle fineness≤5 millimeter after weathering.
The production method of the chlorite after acidifying takes first acidifying to carry out compounding ingredient again, can avoid sulfuric acid and quick dissolved sodium silicate, polyvinyl alcohol, Vltra tears and sodium carbonate generation chemical reaction, give full play to raw-material characteristic separately in batching, and obtain complementation, guarantee the chlorite inner quality after acidifying.
According to the needs of quality product, adopt sodium carbonate to adjust the chlorite pH value after acidifying, method is simple.
The present invention makes full use of sun power, wind and rain alternately and with the passage of time, promotes the weathering effect to chlorite raw ore, improves the disintegration effect of chlorite raw ore, accelerates the dispersion of chlorite raw ore.
Chlorite after acidifying has good adsorptivity, thixotropy, oilness, thermostability and plasticity-feature.
Chlorite after acidifying is applicable to produce the filler of sorbent material, suspension agent, lubricant, malthoid, papermaking, agricultural chemicals and fire product.
